This vented disc brake rotor features a directional, slotted and drilled surface designed to enhance heat dissipation and maintain consistent stopping power under demanding conditions.

• Compatible with Mazda Miata vehicles
• Directional slotted and drilled surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Nominal thickness of 20 mm with discard thickness at 18 mm
• Zinc black hat finish with rust-resistant coating
• Four bolt holes with 100 mm bolt circle diameter
• Overall diameter of 255 mm and height of 45 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Black is constructed with a vented rotor design that promotes airflow between the rotor surfaces, helping to prevent brake fade during extended use. The rotor’s surface is both drilled and slotted, which assists in channeling away brake dust, gases, and water, improving pad bite and overall braking consistency. The directional brake surface ensures optimal performance when installed in the correct orientation.

The rotor has a nominal thickness of 20 mm and a discard thickness of 18 mm, providing a clear service limit for safe operation. The hat section is finished in zinc black, offering corrosion resistance, complemented by an overall rust-resistant coating to extend rotor life. With four bolt holes and a 100 mm bolt circle diameter, this rotor fits securely on the Mazda Miata hub assembly. The center hole diameter measures 55 mm, and the stud/lug hole diameter is 13 mm, matching factory specifications.

Applications and Problem Solving

• Replacement for worn or warped brake rotors on Mazda Miata models
• Improves heat dissipation to reduce brake fade during spirited driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor corrosion issues with rust-resistant coatings
• Enhances brake pad cleaning and gas venting through drilled and slotted design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify that the rotor thickness is above the discard thickness of 18 mm before installation. Clean the rotor surface of any protective coatings or oils prior to mounting to ensure optimal pad contact. Use proper torque specifications for the four bolt holes with a 100 mm bolt circle diameter to secure the rotor safely.
